Three new N ‐salicylidene‐ N ′‐aroylhydrazines tridentate ligands have been prepared: N ‐4‐diethylaminosalicylidene‐ N′ ‐(4‐nitrocinnamoylhydrazine (L 1 ), N ‐4‐diethylaminosalicylidene‐ N′ ‐4‐(2,4‐dinitrophenylethylidene)benzoylhydrazine (L 2 ), N ‐4‐diethylaminosalicylidene‐ N′ ‐4‐(6‐nitro‐2‐benzoxazolyl)benzoylhydrazine (L 3 ). From these ligands, mononuclear acentric complexes of Copper( II ) and Palladium( II ), with pyridine as further ligand, have been prepared and characterized, also by single‐crystal X‐ray analysis. These complexes show high second order nonlinear optical activity (EFISH, |µβ| up to 3000·10 −48 esu, incident wavelength 1.907 μm). The properties of metallorganic polymers obtained by grafting commercial poly(4‐vinylpyridine) with ML 1 fragment (M = Cu II or Pd II ) are also reported. (© Wiley‐VCH Verlag GmbH & Co.
